I purchased this new and used it to take photos with my Pentax old lenses at home. I haven't taken it outside. I only tested how the old lenses would perform at home, so it's in very good condition. I no longer use it, so I'm hoping someone else will. This is a used item. It has been stored in a dehumidified storage, but please refrain from purchasing if you are looking for a perfect item. Feel free to ask any questions! Returns and refunds are not accepted. [Compatible Lens Mount]: Pentax K-mount. [Compatible Cameras]: Leica L-mount (Leica, Panasonic, Sigma).

[MF & Infinity Focus] When using this product, there are no electronic contacts, so focusing is MF, and all aperture adjustments are manual. Infinity focus is achievable.
